The fourth pond that I have is only around 1500 gallons and is only two feet deep. This shallow depth is a problem for both regulating the water temperature and keeping the fish safe from the predatory Heron that comes sneaking around occasionally.
After the episodes with this beautiful bird way back in the early part of the year, I finally resolved the issue with the use of a Scarecrow. This gadget has an electric eye that activates it to spray water very noisily resulting in scaring the Heron away. Of course, the Scarecrow is not selective and sprays anything in range that activates it, including me and the dogs. The other problem is that any vegetation that blows in the wind in range of the electric eye, also sets it off. The two that I had installed and activated back earlier in the year added $25.00 a month to my water bill due to their indiscriminate actions. With the water color on the 3000 gallon pond so cloudy, see the earlier blog, I had shut down that Scarecrow and as the vegetation grew in the 1500 gallon pond, shut down that Scarecrow also.
In this case, the vegetation, mainly made up of green and black Taro and Iris had taken over the pond and it was almost impossible to see the water. It was fine when the Taro, which are both fast growing and very tall stood upright but as is often the case with tall plants, as they age they begin to droop and before long, the surface of the pond was just a mass of stalks and leaves. This did help to keep the water cooler and hide the fish from the Heron but was taking oxygen from the water at an alarming rate. Coupled with the tell tale signs of methane and ammonia gasses bubbling to the surface and the loss of five 12 inch Koi and two Goldfish convinced me that I needed to do something and do it fast.
I opted to change into a pair of my old soccer shorts and put on a pair of water shoes that I use in the ponds. I had kicked around the idea of putting on my waders because of the possibility of meeting the Brown Snake but decided against it as it would have been way too hot and uncomfortable. I was also relying the the common sense of the snake to get out of the pond knowing there was a human in it. As it happened, the snake spent his time in his usual spot on the wall between the two ponds sunning himself not more than 5 feet from me at times. It is not a poisonous snake but all snakes will bite when cornered.
It was slow and steady work as I cut back plant after plant. Some I was able to pull up by the roots which was a good thing as I would not have to deal with them again. Others, I just cut back knowing that they would probably regrow and I would have to do this down the road.
After finishing with this part of the job, I had the task of removing the dead material from the bottom of the pond which was much less that I initially figured. Even though I have a Pond-o-Vac vacuum cleaner built especially for ponds, it is usually quicker to get in and physically remove the dead muck and debris using a net. After completing all of the heavy work, I cleaned the skimmer and the filters and checked the pump which is working just fine. I then reactivated another Skippy Filter to help clean the water and finally ended by turning on one of the oxygenators. Now all we have to do is wait for the water to clear.
The next day I worked on cleaning up all of the material that I had cut back and cleared out of the pond and there was a lot of it. I have found that it is easier to use a pitchfork that I happen to own that I know for a fact is almost 100 years old having belonged to Clark, my Stepfather’s brother at the old farm back in New York State. It still works well and is ideal for picking up the long stalks of the Taro. I don’t know how many trips I made to the compost pile but it was a lot. I was a lot cooler the day before when I was working in the pond itself but cleaning up the mess was very hot work in the 90 plus degree weather.
I finally finished the work at least for a while. Things won’t grow as fast during the really hot weather and it won’t be long before it is Fall, only another month. As with the small pond, I had to reactivate another one of the scarecrows with the vegetation out of the way, the few remaining fish that are still alive, are possible food for the ever present threat of the Heron.
This pond is the next on the list to permanently close down in the next year or so mainly because of the shallow depth. I am getting old whether I like it or not and need to start thinking of the future which eventually includes selling this house and moving elsewhere, probably in an assisted living complex. I know that I cannot keep working on things as I presently do and must plan accordingly. It’s hell growing old…
In the mean time you have an incredible garden!
Thanks, it gives me pleasure that all of the work does end in a thing of beauty. Not that I have much to do with it as Mother Nature takes good care of me…
I hope that you were not affected by those severe Texas floods!
No, I am not in a low lying part of town. Austin hasn’t had any decent rain in 2 months let alone any flooding.
You made such a huge difference in one day. I compare your pond to the size of my bog and wonder what took me so long. Oh! Irises!
You are the most active old guy I’ve ever known!
Not sure about the most active but agree with the old guy part…Thanks anyway.
